List of Slides for Haleakala NP and for Other Islands

Island of Kauai

• Pillow basalts form when lava erupts under water.
• Waimea Canyon, the "Little Grand Canyon" has formed by erosion of the soft volcanic rocks on this, the oldest of the Hawaiian Islands.
• Hanapepe Valley also shows the weathered, eroded basalt of an old volcano.

Island of Oahu

• Downtown Honolulu stands out against the blue Pacific Ocean.
• Diamond Head near Honolulu formed during the last stage of volcanism on Oahu.
• The city encroaches upon Diamond Head.
• The steep sides of Diamond Head slant straight down to the water, separated only by a narrow beach.

Island of Maui - Haleakala NP

• Haleakala NP encompasses Haleakala Crater , with cinder cones and young volcanic flows, and Kipahulu Valley to the east.
• Haleakala is not a true crater, since it was formed by erosion rather than by volcanic explosions.
• Exhibits in the Visitors' Center in the ring of Haleakala Crater illustrate the history of the volcano.
• This picture shows the central, eroded, depression of the crater, containing young volcanics.
• In places, the crater wall has been breached; here Kaupo Gap opens to the ocean.
• The history of Hawaii is a story of conflict between the fires of the volcanoes and the waters of the ocean.
